1. A capacitive-type touch panel comprising:

  • a supporting substrate;

    a first transparent conductive layer on an entire inner surface of the supporting substrate;

    a first electrode on the first transparent conductive layer for applying a voltage having a high frequency to the first transparent conductive layer, wherein the first electrode is metal and is formed at each of four corners of the first transparent conductive layer;

    a second transparent conductive layer facing the first transparent conductive layer;

    a second electrode on an inner surface of the second transparent conductive layer, the second electrode formed at a corner of the second transparent conductive layer and connected to an external ground voltage or a metal shielding plate;

    an adhesive between the first and second transparent conductive layers; and

    a passivation film on an outer surface of the second transparent conductive layer.
